Description
Technical field
The invention belongs to technical field of internal combustion engines, be specifically related to a kind of opposed pistons two stroke diesel engine and make up oil spout mechanism.
Background technique
The two stroke diesel engine of opposed pistons, because the particularity of its structure, traditional oil sprayer arrangement can't satisfy the arrangement requirement of diesel engine.Oil spout mechanism is most important to engine performance and reliability, and traditional oil spout mechanism mainly contains the single oil sprayer mechanism of side direction or 180 ° of oil sprayer mechanisms of bilateral.Single oil sprayer mechanism is simple, but with the chamber structure complexity of oil sprayer coupling, the localized heat load is high, combustion performance is poor; The symmetric arrangement mode can be improved the combustion performance of diesel engine, but for multi-cylinder diesel engine, because the diesel engine bottom is motion, the oil sprayer symmetric arrangement can't realize, combination oil spout of the present invention mechanism is applicable to two cylinder abreast-type opposed pistons two stroke diesel engines, effectively improves the combustion performance of diesel engine.
Summary of the invention
Technical problem to be solved by this invention will provide a kind of opposed pistons two stroke diesel engine to make up oil spout mechanism exactly, effectively improves the combustion performance of diesel engine, satisfies opposed pistons two stroke diesel engine arrangement requirement.
Technological scheme of the present invention: a kind of opposed pistons two stroke diesel engine makes up oil spout mechanism, it comprises oil sprayer 1, lining 2, O RunddichtringO 3, adjust pad 4, lining pad 5, pressing plate 6, body 7, cylinder sleeve 8, firing chamber 9, pressing plate cushion block 10, bearing 11, bolt 12 and piston 13, this combination oil spout mechanism has two oil sprayers 1 at least, and oil sprayer 1 bottom is arranged on lining 2 inside, and lining 2 is arranged in the hole of body 7, oil sprayer 1 is arranged on the lining 2 by bolt 12 by pressing plate 6, be provided with O RunddichtringO 3 between lining 2 and the body 7, the zone between oil sprayer bushing 2 front ends and body 7 and the cylinder sleeve 8 is provided with cooling water, adjusts pad 4 and is arranged between oil sprayer 1 lower end surface and the lining 2, lining pad 5 is arranged on cylinder sleeve 8 outsides, lining pad 5 and cylinder sleeve 8 and the sealing of lining 2 joints, firing chamber 9 is in cylinder sleeve 8 inside, and pressing plate cushion block 10 is between the groove of pressing plate 6 and bearing 11.
Oil sprayer 1 adopts 90 ° of vertical layouts in this combination oil spout mechanism.
The projecting height of described oil sprayer 1 is regulated by the thickness of adjusting pad 4.
Oil sprayer 1 with respect to projecting height be 2 ± 0.1mm.
This oil spout mechanism is 90 ° of corresponding two formula firing chamber, shallow whirlpool 9 structures of opening.
Beneficial effect of the present invention: at least 2 oil sprayers of this combination oil spout mechanism adopt 90 ° to arrange that vertically the fuel injection characteristic by control oil sprayer 1 sprays into cylinder with fuel oil in piston 13 relative movement before inner dead point, and high-pressure gas promotes piston 13 motions.This combination oil spout mechanism is applicable to two cylinder abreast-type opposed pistons two stroke diesel engines, effectively improves the combustion performance of diesel engine.
